Research Interests:
Isotropic Multiresolution Analysis
: smooth wavelets and frame scaling functions without directional bias in any number of dimensions, with applications to biomedical imaging (detecting vulnerable plaque in coronary arteries)
Uncertainty principles in filter design
, an
almost-ideal low-pass filter
with optimal time-frequency regularity properties
Redundant encoding of vectors with frames
Wehrl entropy and sharp uncertainty bounds
for coherent state representations in mathematical physics
Logarithmic Sobolev inequalities and phase space bounds
Hilbert spaces with reproducing kernels
Holomorphic representations and Berezin-Toeplitz operators
Wiener-regularized path integrals in quantum mechanics
Diffusion methods in sampling theory
